class RSS::Rss

RSS 2.0 support ↑

RSS has three different versions. This module contains support for version 2.0

Producing RSS 2.0 ↑

Producing our own RSS feeds is easy as well. Let’s make a very basic feed:

require "rss"

rss = RSS::Maker.make("2.0") do |maker|
  maker.channel.language = "en"
  maker.channel.author = "matz"
  maker.channel.updated = Time.now.to_s
  maker.channel.link = "http://www.ruby-lang.org/en/feeds/news.rss"
  maker.channel.title = "Example Feed"
  maker.channel.description = "A longer description of my feed."
  maker.items.new_item do |item|
    item.link = "http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"
    item.title = "Ruby 1.9.2-p136 is released"
    item.updated = Time.now.to_s
  end
end

puts rss

As you can see, this is a very Builder-like DSL. This code will spit out an RSS 2.0 feed with one item. If we needed a second item, we’d make another block with maker.items.new_item and build a second one.
